The Quick and Easy Way to Analyze Numpy Arrays

Image
The quickest and easiest way to analyze NumPy arrays is by using the numpy.array() method. This method allows you to quickly and easily analyze the values contained in a numpy array. This method can also be used to find the sum, mean, standard deviation, max, min, and other useful analysis of the value contained within a numpy array. Sum You can find the sum of Numpy arrays using the np.sum() function.  For example:  import numpy as np  a = np.array([1,2,3,4,5])  b = np.array([6,7,8,9,10])  result = np.sum([a,b])  print(result)  # Output will be 55 Mean You can find the mean of a Numpy array using the np.mean() function. This function takes in an array as an argument and returns the mean of all the values in the array.  For example, the mean of a Numpy array of [1,2,3,4,5] would be  result = np.mean([1,2,3,4,5])  print(result)  #Output: 3.0 Standard Deviation To find the standard deviation of a Numpy array, you can use the NumPy std() function. This function takes in an array as a par

How to Fix datetime Import Error in Python Quickly

Here's a quick resolution for import datetime Python error. The reason is your .py python script name and datetime are the same. I'll show you how this error happens and its resolution.


 datetime import error


Here's the Resolution for ImportError


I've created a script called 'datetime.py.' to check whether the minute value is 'odd' or not. During the import of my python script, I got the import error cannot import name datetime.

My Script: datetime.py

My script's intention is to find whether the minute value is odd or not.

Python Logic


from datetime import datetime
odds = [ 1, 3, 5, 7, 9, 11, 13, 15, 17, 19,
21, 23, 25, 27, 29, 31, 33, 35, 37, 39,
41, 43, 45, 47, 49, 51, 53, 55, 57, 59 ]
right_this_minute = datetime.today().minute
if right_this_minute in odds:
print("This minute seems a little odd.")
else:
print("Not an odd minute.")


ImportError


I have imported my datetime.py from Linux. It gives an error "ImportError: cannot import name 'datetime' from partially initialized module'.



ImportError


The reason for the error is the .py module name and Python package name both are the same.


Resolution

I've renamed the .py module and imported it to Python3. Then, the import is successful.
